组织学重点（Histological emphasis） Histological emphasis Noun interpretation 1. endothelium: single layer squamous epithelium distributed on the inner surface of the cardiovascular and lymphatic vessels 2. mesothelial: single layer squamous epithelium distributed on the surface of pleura, peritoneum and heart capsule 3. glandular epithelium: epithelial tissue with secretory function 4. molecular sieve: the chain of hyaluronic acid is connected with many protein molecules and polysaccharide molecules, forming a structure with many molecular micropores, which can prevent the expansion of materials larger than the molecular gap 5. hemogram: the morphology, quantity, proportion and hemoglobin content of blood cells and platelets 6. hematopoietic stem cells: the most primitive hematopoietic cells that can proliferate and differentiate into various blood cells. They have strong proliferative ability, potential differentiation ability and self-renewal ability 7. sarcomere: a segment of myofibrils between two adjacent Z lines, including the 1/2I band, the +A band, and the +1/2I band, and is the structural and functional unit of the myofibrils 8. intercalated discs: the adjacent parts of the myocardial fiber are connected, and the thick wire is dyed deep under the light microscope, which is vertical or stepped like the long axis of the muscle fiber. It can synchronize and relax the myocardial fibers and become a functional whole 9., three conjoined: the structure of the final pool on both sides of the transverse tubule 10. blood brain barrier: the barrier between the blood and brain tissue, which is composed of continuous capillary endothelial, endothelial basement membrane and glial membrane formed by astrocyte. The structure that restricts the entry of macromolecules into brain tissue 11. synapse: the interface between neurons or between neurons and effector cells that transmits information 12. nerve fibers: nerve fibers or oligodendrocytes formed by axons or long dendrites and
